A.5. Boot Loader Configuration

A software boot loader is used to start Red Hat Linux on your computer. It can also start other oper 

ating systems, such as Windows. If you are using a Red Hat Linux software boot loader (GRUB or

LILO), it will be detected automatically.

Figure A 3. Upgrade Boot Loader Configuration

On the Boot Loader Configuration Screen, your options are:

Update boot loader configuration   Choose this option to keep your current boot loader configura 

tion (GRUB or LILO depending on what you have currently installed) and have updates applied.

Skip boot loader updating   Choose this option if you do not want to make any changes to your

current boot loader configuration. If you are using a third party boot loader, you will want to skip

updating your boot loader.

Create new boot loader configuration   Choose this option if you want to create a new boot loader

for your system. If you currently have LILO and want to switch to GRUB, or if you have been using

boot diskettes to boot your Red Hat Linux system and want to use a software boot loader such as

GRUB or LILO, you will want to create a new boot loader configuration (see Section A.5.1 for more

information).

Once you have made your selection, click Next to continue.

A.5.1. Creating a New Boot Loader Configuration

In order to boot the system without a boot diskette, you usually need to install a boot loader. A boot

loader is the first software program that runs when a computer starts. It is responsible for loading and

transferring control to the operating system kernel software. The kernel, in turn, initializes the rest of

the operating system.

The installation program provides two boot loaders for you to choose from, GRUB and LILO.
